As for the first picture;
That looks like the Princess, I don't have a confirmation on who that is .. (interesting picture btw)
& for number two, I'm pretty sure Lelouch did die because Nunnally was there when he died, so I think thats just a random person (C.C is talking to herself/spirit?). Of course, my assumption could be wrong...
This is why I love Code Geass.. keeps you thinking with twists and turns!
